hyd clutch problem

i installed a tremec 5 speed, spacer, with a mcleod clutch and pressure plate, with their hyd. release bearing and wilwood clutch master. it took a few trys to get the release bearing,(they sent the wrong one twice) all of this into a 1963 fairlane. i bought a new brake master cyl and re-plumbed it to exit the brake lines to the passenger side of the car. i installed the clutch master next to it on the drivers side to get a good straight path to the clutch pedal. once done the clutch pedal was extremely hard, even after bleeding several times. i never drove it much as i am always upgrading other parts. i drove it around to a friends the other day and when i got back in it, it would not go into gear. after inspecting everything, i found that the clutch rod had bent over. more than 45 degrees. what would cause the pedal to be so stiff? especially stiff enough to bend the clutch rod. as stiff as it was it still went into gear and all. any thoughts??????oh and wilwood was not any help. first photo shows the connector 2nd photo shows the rod.

2112,

What is the bore size of the master cylinder? It must be matched to the hydraulic throwout bearing. If you are using the Mcleod bearing, the instruction sheet that came with the bearing should give you some guidance. I believe the bearing is designed to work with a 3/4" bore cylinder. The larger the bore, the harder the pedal feel.

The clutch pedal can also be pushed too far (over-travel) and do damage to the clutch. The pedal may need a stop on it to make sure that you don't push it too far and damage the clutch or throwout bearing.

Another thing to look at is the pedal ratio. It should be around 6-to-1. Rather than give you the wrong information on how to measure the ratio, see the Mcleod instructions.

If you were like me, I didn't receive any setup instructions with my McLeod bearing, and there's a lot of useful information on it. You may want to call Mcleod, they are very helpful on the phone.

Hope this helps.

Steve

i used the 3/4 master. i will check the ratio. the bearing came with no instructions. i used the rod that came with the master, and it make for a short throw, in other words the clutch pedal was lower than the brake pedal which i thought would be good. less distance to engage for faster shifting. but it was still extremely stiff... my clutch is on Viagra....lol...
